Wifi keeps reenabling on Sonos Port with Ethernet connection

I’m running a mixed environment in Ubiquiti with about 10 devices. 4 are hardwired and the rest on my Wireless network. My goal is to not run sonosnet - and I don’t think I am.

However, one of my Ports won’t stay disconnected to wifi. I can disable it from the app, but a few minutes later it reenables it.

What’s funny is that my router shows it as hardwired.

I saw the advice in the following post, but it was 4 years ago… about hardwiring directly to the router (this is two switches in currently. Seems odd, but does that still work?

Any unwired Sonosnet compatible devices will connect to Sonosnet instead of your Wi-Fi if possible.

Yup.. that was it. I thought I had moved everything to wifi direct or ethernet. Turns out that the older Play 1s and 3s kept pushing the wifi back on the Port so they could use Sonosnet. My router made it look like they were connected directly via wifi, but in retrospect, I’ll be they were just mirroring the wifi from the Port. Unifi is notorious for showing weird things in the UI sometimes.

Thanks everyone.

I’d be tempted, since you have other devices, to factory reset it. Due to those other devices, you shouldn’t lose any information, it will copy over from the other devices when you’re-add it. The advantage of a factory reset in this case is that you’re essentially reloading the firmware that it operates on.

Seems like it’s behaving contrary to normal right now. But if this doesn’t work, I’d be tempted to submit a system diagnostic within 10 minutes of experiencing this problem, and call Sonos Support to discuss it. Don’t post the resulting diagnostic number here, they get sensitive about GDPR.

There may be information included in the diagnostic that will help Sonos pinpoint the issue and help you find a solution.

When you speak directly to the Support staff, they have tools at their disposal that will allow them to give you advice specific to your network and Sonos system.

I’d follow the advice from 4yrs ago. No reason why that reasoning would no longer apply today.

You probably know this, but are running Sonosnet if you have any Sonosnet compatible devices wired to Ethernet and their radios are enabled.

With the radio disabled connecting Sub or Surrounds can be a problem.

However, one of my Ports won’t stay disconnected to wifi. I can disable it from the app, but a few minutes later it reenables it.

My first thought is that the Ethernet connection is unstable for some reason causing the switch, given our limited access to Sonos internal data a diagnostic and support call might answer that.

I gave up on wired here to eliminate the Sonosnet and free up the wifi channels it was using.

I did ask that Sonos consider offering a "disable Sonosnet" option for users who wanted or needed wired connections but didn't want Sonosnet active.

Your reasoning for the WiFi being re-enabled on the Port does not make any sense unless there is a bug in the software.

An unwired device should not have any impact on the Disable WiFi selection on the Port.

There would be little point having the Disable WiFi option in the app if an unwired device was allowed to enable the setting again and activate SonosNet, which was specifically turned off.

Maybe UniFi is blocking ethernet port the Port is connected to STP misconfiguration in the UniFi Network?

Disable STP on the UniFi switch ports that Sonos is connected to.

Personally (I did this several years ago), I would disconnect all ethernet from Sonos, just use the UniFi WiFi. This will free up a 2.4GHz channel for your UniFi, as per @Stanley_4 suggestion. The UniFi Network App will give you more detailed WiFi connection information, than the Sonos Matrix will, and eliminates any STP issues.
